摘要： An organic light emitting display device includes a pixel unit, a scan driver, a data driver and a voltage generation unit. The pixel unit includes a plurality of pixels coupled to a plurality of scan lines and a plurality of data lines, where each of the pixels includes an organic light emitting diode. The voltage generation unit is coupled to the pixel unit through one power line which provides the common supply voltage to the pixels. Each of the plurality of pixels includes a voltage drop unit, each voltage drop unit generates a respective drive voltage by dropping a voltage of the common supply voltage, and turns on the organic light emitting diode to emit light with a luminance corresponding to a voltage of the drive voltage based on a logic level of the data signal. The organic light emitting display device increases an aperture ratio.
